如何确定 Windows 操作系统字体是否支持粗体或斜体

Question

How do you determine if a particular font supports bold or italic regardless whether it's a True Type or Type 1? I have the following scenarios relating to embedding a Flex font issue:

• I have 3 TTF font files called Unknown1, Unknown2 and Unknown3. Let's say they're installed for now
• When I embed the fonts, Flex tells me that Unknown2.ttf doesn't support a bold weight or Unknown3.ttf doesn't support an italic style

My question is, how did Flex knew all of that? I've been searching through C# and Java libraries but none of them seem to offer what I need. Or apparently, I'm not looking hard enough. Anyways, are there classes in Java or C# that can provide me with some signature like:

Font unknownFont = Font.getFontFromAnyDirectory("Unknown2.ttf"); unknownFont.supportsAnyStyleCalled(Font.BOLD);//Returns false. unknownFont.supportsAnyStyleCalled(Font.ITALIC);//Returns true. // unknownFont = Font.getFontFromAnyDirectory("Unknown3.ttf"); unknownFont.supportsAnyStyleCalled(Font.BOLD);//Returns true. unknownFont.supportsAnyStyleCalled(Font.ITALIC);//Returns false.

Answer 1

在 C# 中，您可以通过调用FontFamily.IsStyleAvailable 来实现

Answer 2

I know the question is pretty old, I had the same problem and the solution is stated in C# get font style from .ttf .

You can use:

GlyphTypeface ttf = new GlyphTypeface(new Uri(@"C:\Windows\Fonts\calibrii.ttf"));
Debug.Print(ttf.Style.ToString()); //=Italic or Normal
Debug.Print(ttf.Weight.ToString()); //=Bold or Normal
